Compare active transport to passive transport?

Answer 1

Active transport requires energy, whereas passive transport does not. Passive transport is normally something moving from an area of high concentration to low concentration (with the grain). Active transport is something moving from an area of low concentration to an area of high concentration(against the grain).

Answer 2

Active and passive transport are alike because they both transport. They are different because active transport requires cellular energy to move molecules through a cell membrane while passive transport "dissolves" molecules WITHOUT energy.

Answer 3

Contrasts: Firstly, the movement of Particles, where Active Transport moves against its concentration gradient, where it can move from a low concentration to a high concentration, such as the transport of Ions and Glucose, whereas Passive Transport moves with its concentration gradient, from a high concentration, to a low concentration to level the concentration, such as the movement of water in Osmosis and the movement of Particles in Diffusion. Secondly, the mechanisms involved in Active Transport and Passive Transport, as pumps and channels are needed to move specific particles or proteins against the concentration gradient, whereas Passive Transport involves lower mechanisms to move particles across the membrane, as small particles move across the Phospholipids. Finally, the last contrast is the involvement of ATP in Active Transport, but not in Passive Transport. ATP is a class of Energy and energy is needed more in Active Transport than Passive Transport as particles need to be forced against the concentration gradient. Also the particles will be large and need a "helping hand" during the process of them moving against its concentration gradient. Comparisons: Firstly, Active Transport and Passive Transport are both involved within the Phospholipid Bilayer naturally. This is because Active Transport mechanisms, such as protein channels, are embedded with or lie on the Phospholipid Bilayer. Also in Passive Transport, molecules slip within the Phospholipids and out on the other side. Finally, Active Transport and Passive Transport naturally transport Partilcles across the Phospholipid Bilayer, to supply the cell with its requirements. Active Transport does this by Protein Channels and Vesicles, whereas Passive Transport use methods like Diffusion and Osmosis

Answer 4

Active transport....- Requires Energy.- Against concentration gradient.

- Primary and secondary transport.

- Proteins, ions, larger cells, bacterial cells, sugar.

Passive transport...- Doesn't require energy.

- With concentration gradient

- Diffusion, facilitate diffusion, osmosis.

- Water, elements, soluble in lipids.

Both....- Transport material.

Answer 5

active transport uses energy in the form of ATP from the mitochondria whereas passive transport doesn't use energy

active transport move against the concentration gradient while passive transport moves across the concentration gradient

(passive transport = osmosis, diffusion)

Answer 6

because one requires energy and one does not
